Weir joins CNN as an anchor and Chief Innovation Correspondent, the network announced. Weir is being replaced on the ABC News show by Dan Harris, as we reported earlier today.

"The former anchor of ABC News’ ‘Nightline’ will work with producers to develop original programming across the schedule. He will join CNN in November, and be based in New York," CNN said in its announcement.

Said CNN Worldwide President Jeff Zucker: “Bill’s range, sensibility and curiosity set him apart. He brings a unique storytelling style, perspective and sense of humor to CNN, and he will be a key player as we continue to expand our lineup.”

CNN’s announcement adds: "In addition to his anchoring and development roles, Weir will bring his forward-looking perspective to coverage of the innovation and technology space. After filing groundbreaking reports from around the world on the likes of Apple, Microsoft and Facebook he will continue to document the pace of leading-edge innovation for CNN."

Weir added: “I’m ecstatic to join a team with such vast resources and such strong commitment to covering our world. ‘Nightline’ was a blast and while I’ll always be indebted to my ABC friends this is a chance to mix journalism and creative storytelling in a whole new way. I can’t wait.”
